I have a quadro 4000 in a dell t5500. I am running windows 7 professional 64 bit. I have 6gb of ram. My question is why is it that AutoCAD and other programs say that I only have 733 MB of available video memory? Windows says I have 4862 MB of video memory. Also, AutoCAD says that my card is not certified if I use the nvidia drivers but it is certified with the AutoDesk drivers but the Nvidia drivers work three times better. I have exhasted every other option I can think of to come to a solution to these problems.
